Titanium and Stainless side by side
+++
We are planning on using both Titanium and Stainless sheet steel
in a enclosure. We will be completing a passivation process on both
of these. Is there any issue with any type of rusting or
contamination with using these 2 unlike materials that I should be
aware of. This is a medical application in which both of these
materials will be auto claved in the future. If so any suggestions on
how to protect the materials due to this?

There are some important questions here, like what GRADE of
stainless (I assume austenitic) and how is it connected, etc. Any
time you have two dissimilar metal in an aqueous medium you CAN get a
galvonic effect that COULD cause corrosion. If you are using good
metals this is minimized. If passivated properly you should be okay.
Putting a non-conductive insulation between the two metal will
help, if possible.
You need to test.
